GAGE BROTHERS & CO.
The American Luxfer Prism Co., Chicago, Ill.
|Chicago, December 24, 1897.|
In regard to the Luxfer Prisms placed by your
company in building we occupy, being Nos. 118-120 Wabash avenue, would
say that the results derived are highly satisfactory, and make good the
representations made by you before entering upon the work.
On the first floor, notwithstanding the
disadvantage of our location, owing to the large elevated road structure
in front of our building, and the high building opposite in alley in rear,
your Prism system of lighting enables us, on an ordinary bright day, to
distinguish and match colors in the center of floor without artificial
light. This, in the past, we have not been able to do on the brightest
of days, notwithstanding we have been using four arc lights and quite a
number of incandescent lights most of the time.
On the second, third and fourth floors, we have
had no occasion to use artificial light during business hours, since
your system of lighting was put in.
Your work, as a whole, is highly satisfactory,
and we are sure will enable us to make quite a savings in our lighting
Yours very truly,
|By Geo. Ebeling, Secretary.
